HAY-TEDDER.

SPECIFICATION forming part of Letters Patent No. 617,202, dated January 3, 1899.

Application filed $eptemher 1, 1898. Serial No. 689,992. (No model.)

To all whom, it may concern.-

Be it known that I, J OSEPH A. SWANsoN, a citizen of the United States, and a resident of Qrion, in the county of Henry and State of Illinois, have invented certain new and useful Improvements in Hay-Tedders; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to prevent detrimental accumulation of hay on fork-tedders and it consists in the hay-tedder attachments hereinafter particularly set forth, with reference to the accompanying drawings, and subsequently claimed.

Figure 1 of the drawings representsa plan view of a portion of a fork hay-tedder provided with attachments in accordance with my invention; Fig. 2, a partly-sectional elevation of the same on the plane indicated by line 2 2 in the preceding figure, and Fig. 3 a partly sectional rear view of a tedder-fork provided with one of the aforesaid attachments.

Referring by letter to the drawings, A represents a portion of the front transverse timber of a hay-tedder frame; B, the driven shaft having a plurality of crank-loops 0, disposed in zigzag order; D, the fork-bars in connection with the cranks, and E the links connected at their extremities to the upper ends of said bars and said frame-timber.

A spring-wire fork F, coiled and looped at its upper end, engages a gas-pipe arbor Gin brackets at the lower end of each bar D, and a flat spring H, fast at its upper extremity to said bar, bears on the fork-loop.

While the construction and arrangement of parts thus far described is common in the art of hay-tedders, its showing is herein made for the purpose of clearly demonstrating the application of my hay-tedder attachments hereinafter set forth.

Herein shown made fast to the under side of the rearwardly-entended timbers I of the tedder-frame are preferably flat metal sup ports J, and as a matter of convenience these supports and bearings for crank-shaft B are held to said timbers by the same means. The supports J incline upward toward the rear for a predetermined distance, then continue horizontally far enough to form seats for a rigidly-connected cross-bar K, and have upturned rear terminals at obtuse angles to said seats, these terminals being in connection with another cross-bar L, the latter, with said supports and former cross-bar, constituting a hay-fender.

At intervals of its length the cross-bar K of the hay-fender is provided with depending pins M, arranged to come between the tines of tedder-forks about the time these forks finish their lift incidental to revolution of the crank-shaft 13 above specified. 7 Other pins N depend from the cross-bar K of the hayfender on planes between the tedder-forks, and these latter fingers alternate with those aforesaid.

'lhe movement of the tedder-forks being shown by dotted arrow lines in Fig. 2, it will be apparent that the depending fingers of the aforesaid fender will strip hay from said forks, and owing to the general construction and arrangement of parts constituting the at tachment thus far disclosed it is evident that hay cannot accumulate on the tedder whether the latter is driven with the wind or against the same.

Sprung into the ordinary tubular arbor G of each tedder-fork are inwardly-bent ends of a triangular loop P, having its apex held by a clip Q on the bar D of said fork under the spring H, fast to said bar. This application of loop P is best illustrated in Fig. 3, and said loop constitutes a guard that prevents hay from becoming entangled with a fork.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An attachment for a fork hay-tedder, the same comprising upwardly-inclined rearwardly-extended supports having horizontal continuations and rear terminals inclined upward, a cross-bar in connection with the horizontalportions of the supports, another crossbar connected to the rear terminals of said supports, and hay-stripping fingers depend ing from the former crossbar.

- 2. An attachment for a fork hay-tedder, the same comprising upwardly-inclined rearwardly-extended supports having horizontal continuations and rear terminals inclined upward, a cross-bar in connection with the hori- 1o nected to the fork-bar, this attachment serving as a guard to prevent hay from becoming entangled with the adjacent fork.

In testimony that I claim the foregoingl have hereunto set my hand, at Orion, in the county of Henry and State of Illinois, in the 15 presence of two Witnesses.

JOSEPH A. SWVANSON.
